Patent GB-1282541-A (GB)
Title: Telecommunication cross-bar switches
Inventor: HOLDSWORTH ROBERT
IPC: H01H67/26
Filed: 1970-01-12
Abstract: 1282541 Automatic exchange equipment PLESSEY CO Ltd 29 Dec 1970 [12 Jan 1970] 1346/70 Heading H4K A cross-bar switch has the self-latching springsets at the cross-points operated by the respective bridge and select magnets with the latter releasing after the connection is made so that the connection is held by the bridge magnet. Additional row and column conductors are provided and are interconnected by the springset at the operated cross-point to enable the select magnet circuit so that it can be re-operated to close a further cross-point in the same row when the respective bridge magnet is operated. In the switch shown, the switch cross-points are 11, 12, 21, 22 and the re-operate cross-point contacts are r11r, r12r, r21r, r22r which make connection to relays RM1 or RM2 thus closing a respective contact so that the respective select magnet SM1, SM2 can be operated again. As shown, bridge magnet BM2 and select magnet SM2 have been operated to close cross-point 22 and select magnet SM2 has been released by contact OS2 opening. Contact OS2 is inhibited from closing again by an engaged test circuit (not shown). In some circumstances it is required to transfer the output connection 02 from input I2 to input I1 which necessitates operation of bridge magnet BM1 and reoperation of select magnet SM2. Such circumstance occurs in a telephone exchange when a subscriber on 02 has to be transferred from a register on I2 to a junction supervisory set on I1 without breaking the subscriber loop. Select magnet SM2 can be re-operated to operate cross-point 21 since relay RM2 is operated through the re-operate contacts r22r, bc2 of cross-point 22. Crosspoint 22 is released by de-energizing bridge magnet BM2. A similar arrangement is described for a cross-bar switch having auxiliary and main rows of conductors, Fig. 4, 5 (not shown). In this case a diode is inserted in the connections to the re-operate column conductor to ensure that the system responds only to a re-operate signal.

Title: Improvements in or relating to the supply of scavenge and combustion air to two-stroke cycle internal combustion engines
IPC: F02B37/04
Filed: 1951-01-24
Abstract: 736,581. Supercharging and scavenging. DOXFORD & SONS, Ltd., W., PURDIE, W. H., and JACKSON, P. Jan. 18, 1952 [Jan. 24, 1951], No. 1834/51. Class 7(2). In a two-stroke multi-cylinder Diesel engine of the type having in each cylinder two opposed pistons each connected to a common crankshaft by one or more connecting rods and having one or more reciprocating pistontype air-compressors 1, 2, Fig. 3, for supplying scavenging and combustion air, the or each compressor being engine driven by linkage from the piston or connecting rods, there is provided a turbo-blower 8 actuated by the engine exhaust independently of the engine mechanism and arranged to supply air to the piston compressors 1, 2 thereby to increase the compressor output according to the volume and pressure of the exhaust gases. The compressors 1, 2, which are driven from the crossheads of the two end engine cylinders 6, 7, deliver air into the engine casing 16 from whence it passes to the engine. The turbo-blower 8 delivers air through an intercooler to a manifold 13 which is the common inlet to compressors 1 and 2. A bypass pipe 14 with a weight or spring closed non- return valve 15 therein may be provided around the compressors, the valve 15 opening when the pressure on the blower side of pipe 14 exceeds the pressure in the engine casing 16. In a modification, three compressors 20-22, Fig. 4, are driven from the end cylinders of a sixcylinder engine whilst two turbo-blowers 26, 27 are each driven by the exhaust gas from three cylinders and feed air to a manifold 31 through intercoolers 33, 34 and pipes 30, 32, respectively; by-pass pipes 35, 36 with non-return valves therein may be provided between pipes 30, 32 and the engine casing 39. Two compressors may be provided at opposite ends of the engine and each of the two blowers is arranged to deliver air independently to the compressors feeding the cylinder from which each blower is driven. More than two blowers may be provided each driven by the exhaust gases from a cylinder or group of cylinders. In a further modification, three piston compressors 40-42, Fig. 7, have their inlets connected to a reservoir 49 supplied with air from a turbo-blower 43 through a pipe 47 and an intercooler 48 ; the turbo-blower is arranged vertically and mounted at the rear centre of the six engine cylinders. The compressors deliver into the engine casing 51 whilst a by-pass pipe 50 and non-return valve 52 may be provided between reservoir 49 and casing 51 so enabling the compressors to be by-passed under given pressure conditions. When a by-pass is provided the capacity of the compressors is only sufficient to deliver the air required by the engine at partial load, the by-pass enabling additional air to be supplied direct from the turbo-blower. Specifications 244,032, [Class 7(ii)], and 580,704 are referred to.

Title: Improvements in and relating to blocking oscillator circuits
Inventor: LEVELL DEREK ALFRED
IPC: H03K3/16
Filed: 1954-01-21
Abstract: 765,472. Pulse generator circuits. LEVELL, D. A. Jan. 7, 1955 [Jan. 21, 1954], No. 1834/54. Class 40(6) The amplitude of a pulse generated by a blocking oscillator circuit is maintained substantially constant by applying to an electrode of the blocking oscillator tube when the predetermined amplitude is attained a voltage which maintains the current in the tube substantially constant. The Figure shows a blocking oscillator circuit of which the pulses generated have their duration maintained constant by delay line 18. The blocking oscillator tube 12 has trigger impulses applied to its control grid from terminal 10 via diode 11 the negative swing of the grid being limited by diode 20. Tube 25 is normally cut off by the negative voltage applied to its control grid from terminal 31. When a positive trigger impulse is applied at input 10 the blocking oscillator tube 12 is cut off, the anode voltage goes negative and due to the action of transformer 13 a positive pulse is generated at terminal 24 and is ultimately terminated by reflection of a negative pulse to the control grid of tube 12 from the end of delay line 18. If the positive pulse at output 24 tends to increase in amplitude a positive voltage is applied via frequency compensated attenuated circuits 26, 28, 27, 29 to the control grid of pentode 25, the resulting negative voltage at its anode being applied to the screen grid of blocking oscillator tube 12 to maintain the current in this tube constant. Thus any tendency for the pulse at output 24 to change in amplitude is compensated by the feed-back circuit comprising pentode 25. If it is required to change the amplitude of the output pulse at 24 whilst maintaining a substantially constant duration this may be effected by adjusting the setting of potentiometer 30.
